Calling Sequence
[Ro,Theta]=polar(A)
Parameters
- A
real or complex square matrix
- Ro,
real matrix
- Theta,
real or complex matrix
Description
[Ro,Theta]=polar(A) returns the polar form of
A i.e. A=Ro*expm(%i*Theta)Ro symmetric >=0 and Theta hermitian
>=0.
Examples
A=rand(5,5);
[Ro,Theta]=polar(A);
norm(A-Ro*expm(%i*Theta),1)
